THRASHlNG-MACHINE.

PECIFICATION forming part of Letters Patent No. 317,201, dated May 5, 1885.

Application filed January 13, 1885. (No model.)

To all whom it may concern.-

Be it known that I, ANDREW J. REDMAN, of La Crosse, in the county of Bush and State of Kansas, have invented certain new and useful Improvements in Thrashing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to thrashing-machines, the object being to provide the cylinder-casings of such machines with transverse strips to serve as dust-stops, and arranged and com bined with the casing as hereinafter fully described.

The invention consists in the combination, with the cylinder-casing of a thrashing-machine, of transverse strips constructed and arranged as pointed out in the claims hereinafter made.

In the drawings, Figurel represents in perspective the cylinder cap or casing of a thrashing-machine provided with my improvement. Fig. 2 is a sectional view of the same.

A represents the cylinder-cap of the machine-casing provided with a front cross-bar, B, to the inner side of which is secured an upwardly-inclined strip, 0, extending across the casing, and having its upper edge, 0, beveled, as shown. This strip 0 is practically an inward extension of the crossbar B of the cap, and it forms in connection with the latter a pocket or dust-space, F, which receives the dust carried by the eddy created in the forward angle of the cylinder-cap, and prevents it being driven down again in front of the cylinder and escaping into the faces of the operators. When the cylinder-cap is thrown up, this empties the receptacle. By this construction the cap A is made of proper size to protect the cylinder and its teeth, and to act as an eddy-chamber to retain the dust.

1) represents a strip secured to the rear edge of the top E of the casing, and downwardly and inwardly inclined. The lower edge, (I, of this strip is beveled to permit of its resting as near as possible to the cylinder without interfering with the revolution of the latter. The strip D prevents the straw from being carried up by the cylinderteeth, and forms, in connection with the adjacent parts of the cylinder-cap, a dead-air and dust space, G.

I am aware that transvese dust-stops have heretofore been used with thrashing-machines hence I do not broadly claim a transverse dust-stop; but

What I claim is- 1. In combination with a thrashing-machine cylinder, the cap A, constructed with a vertical front wall or cross-bar, and an extension, 0, projecting inwardly and upwardly inclined to form, in connection with said front wall of the cap, an eddy-chamber and dust-space, F, substantially as set forth.

2. The combination, with the cylinder and its cap, of inwardly-inclined strips 0 and D, the former being secured to the vertical front wall of the cap and inclined upwardly therefrom, and the latter in rear of the cylinder to form dead-air and dust spaces F and G, and having beveled edges adjacent to the cylinder, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

ANDREWV J. REDMAN.
